Product Features & Specifications

   Our precision tubes offer improved dimensional accuracy with outer diameter tolerance typically within ±0.05mm and wall thickness tolerance within ±0.03mm. The consistent straightness (≤0.5mm/m) and reliable roundness provide a solid foundation for subsequent manufacturing operations, helping to reduce initial machining time and material waste.

  The superior surface quality with roughness levels reaching Ra≤1.6μm (and Ra≤0.8μm for premium grades) presents a clean, uniform surface finish that serves as an excellent starting point for further processing or coating applications. The absence of significant surface defects minimizes the need for extensive surface preparation before final machining or assembly.

  Through controlled heat treatment processes including annealing, normalizing, and stress relieving, these tubes achieve balanced mechanical properties that can be tailored to specific application requirements. This flexibility allows customers to select the appropriate combination of strength, toughness, and machinability for their particular manufacturing needs.

Applications & Material Options

  These precision tubes serve various industrial sectors including:

  Automotive components: Shock absorber cylinders, steering shafts, and transmission parts

  Hydraulic systems: Cylinder barrels and hydraulic line pipes

  Mechanical parts: Shafts, sleeves, and structural components

  Industrial equipment: General machinery and precision instrument applications

  We offer multiple material grades including carbon steels and alloy steels, with the capability to provide stress-relieved, normalized, or annealed conditions according to your processing requirements. This ensures the tubes arrive in the most suitable condition for your specific manufacturing operations.
